Description

Rotor brake device for spinning reel

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a rotor brake device for a spinning reel, and more particularly to a rotatably mounted relative to a reel body according to a swing of a bail arm in which a wobble is a wire take-up posture and a wire release posture. Rotor braking device for a spinning reel of a rotor brake.

In a spinning reel, a guide ring arm for guiding the fishing line to the reel is swingably mounted to the rotor. The guide ring arm is configured to obtain two postures of a wire take-up posture when the fishing line is wound up to the reel and a line release posture when the fishing line wound around the reel is successively delivered, according to the swing. When the rotor is freely rotatable when the bail arm is in the wire release posture, the guide ring arm can be restored to a state in which it is difficult to perform the operation such as the wire take-up posture. Therefore, it is known to provide a rotor brake device that prevents rotation of the rotor when the bail arm is in the line release posture. For example, in the cited document 1, a moving member that moves along with the swing of the bail arm is provided, and the bail arm is prevented by bringing the cover attached to the front end of the moving member into contact with the braking member provided on the reel body. Rotation of the rotor in the line release position. Further, in the cited document 2, a brake member that is engaged with the moving member and frictionally engaged with the reel body is relatively rotatable, and the brake member is frictionally engaged with the reel body to prevent the rotor from rotating.

[Problem to be Solved by the Invention] For example, in the brake device of the above-mentioned document 1, if the contact position of the cover that comes into contact with the brake member is shifted due to a manufacturing error, a mounting error, or the like, the amount of compression of the cover fluctuates. If the amount of compression of the cover fluctuates, the braking force is deviated, and it is difficult to obtain a stable braking force. In the cited document 2, if the engagement position of the moving member that is engaged with the brake member is shifted due to a manufacturing error, a mounting error, or the like, the brake member and the moving member are not well engaged. It is impossible to obtain a specific braking force. Further, since the force by which the moving member presses the brake member toward the reel body varies depending on the engagement position of the moving member, the braking force is deviated, and it is difficult to obtain a stable braking force. An object of the present invention is to stabilize a braking force in a rotor brake device for a spinning reel. [Technical means for solving the problem] The rotor braking device of the spinning reel according to one aspect of the present invention rotates relative to the reel body in accordance with the swing of the bobbin arm in which the swing is the wire take-up posture and the wire release posture.

The moving member is disposed on the rotor so as to be movable in the first position corresponding to the wire take-up posture and the second position corresponding to the wire release posture in conjunction with the guide arm, and has a braking member when moving to the second position. Prominent protrusion. The elastic member is attached to the protruding portion of the moving member, and is in contact with the outer peripheral surface of the braking member when the moving member moves to the second position. The adjusting member is disposed between the protruding portion of the moving member and the elastic member to adjust the position of the elastic member. In the rotor brake device for the spinning reel, since the position of the elastic member can be adjusted by the adjustment member, the elastic member can be disposed at a position where a specific braking force is obtained when the elastic member comes into contact with the brake member. Thereby, stable braking force can be obtained without being affected by manufacturing errors or mounting errors. Preferably, the brake member has a plurality of engaging portions on the outer circumference. The protruding portion of the moving member is engaged with the engaging portion of the braking member when the moving member moves to the second position. The elastic member is in contact with the outer peripheral surface of the brake member when the moving member moves to the second position. In this case, a stable braking force can be obtained without being affected by manufacturing errors or mounting errors. Preferably, the adjustment member adjusts the position of the radial direction of the elastic member. In this case, in addition to the above effects, the force of pressing the elastic member by the elastic member can be adjusted by the adjustment member, so that the adjustment of the braking force can be easily performed. Preferably, the adjustment member is a spring member that urges the elastic member toward the radially inner side. In this case, a stable braking force is obtained in the same manner as the above-described effects, and the time adjustment work is saved at the time of assembly, so that the efficiency of the assembly work can be improved. It is preferable that the elastic member is a cover member made of rubber. In this case, the elastic member can be easily attached to the moving member, and the adjustment member can be held at the inner peripheral portion of the elastic member. [Effect of the Invention] According to the present invention, in the rotor brake device of the spinning reel, the braking force can be stabilized.

In the present embodiment, the brake member 21 is, for example, an elastically deformable annular member such as rubber. The brake member 21 is formed in a substantially D shape when viewed in the axial direction, and is attached to the mounting groove 1d formed in the cylindrical portion 1c of the reel body 1. The outer peripheral surface of the brake member 21 is formed by a curved surface 21a whose outer edge is smooth at the front end. The outer peripheral surface of the brake member 21 has an annular portion 21b and a straight portion 21c. The elastic member 22 described below is in contact with the annular portion 21b. The switching member 17 constituting one of the guide ring reversing mechanisms 5 is disposed on the outer peripheral portion of the straight portion 21c. The moving member 15 constitutes a part of the guide ring reversing mechanism 5 and also constitutes a part of the rotor braking device 6. The first protruding portion 15a of the moving member 15 is bent toward the center of rotation of the rotor 3. The first projecting portion 15a is located radially outward of the brake member 21 when the moving member 15 is moved from the first position to the second position, and the front end of the first projecting portion 15a faces the annular portion 21b of the brake member 21. The elastic member 22 is, for example, a rubber-made cover member that is elastically deformable, and the front end is formed in a spherical shape. The elastic member 22 has an inner space that can accommodate the first protruding portion 15a of the moving member 15 and the adjusting member 23. The front end of the first protruding portion 15a of the moving member 15 is housed in the internal space of the elastic member 22. In other words, the first protruding portion 15a of the moving member 15 is covered by the elastic member 22. As shown in FIG. 4, the elastic member 22 is disposed at a position where the tip end overlaps at least a part of the annular portion 21b of the brake member 21 when viewed in the axial direction. Thereby, the elastic member 22 comes into contact with the annular portion 21b of the brake member 21 as the guide arm 4 swings in the line release posture and the moving member 15 moves to the second position. When the elastic member 22 comes into contact with and rubs against the annular portion 21b of the brake member 21, the rotation of the rotor 3 when the bail arm 4 is in the line release posture is braked. The adjustment member 23 is housed in the internal space of the elastic member 22, and is disposed between the front end of the first protrusion 15a of the moving member 15 and the bottom surface of the internal space. In the present embodiment, the adjustment member 23 is, for example, a shim or a spacer, and adjusts the position of the elastic member 22 in the radial direction. Thereby, the elastic member 22 can be disposed at a position where a specific braking force can be obtained, so that a stable braking force can be obtained without being affected by manufacturing errors or mounting errors. Further, by adjusting the position of the elastic member 22 in the radial direction by the adjustment member 23, the force by which the elastic member 22 presses the brake member 21 can be adjusted, and the braking force of the rotor brake device 6 can be easily adjusted.

In addition, in FIGS. 6 and 7, the same components as those in the first embodiment are denoted by the same reference numerals as in the first embodiment. The brake member 121 is, for example, an elastically deformable annular member including rubber or the like. The brake member 121 is attached to the mounting groove 101d formed in a ring shape in the cylindrical portion 1c of the reel body 1, and is frictionally engaged with the mounting groove 101d in a relatively rotatable manner. The brake member 121 has a plurality of engaging portions 121a which are formed to extend radially outward from the outer circumference and are formed at a predetermined interval from each other. When the guide ring arm 4 swings into the line release posture and the moving member 15 moves to the second position, the elastic member 22 engages with the engaging portion 121a, and the elastic member 22 comes into contact with the bottom portion 121b of the engaging portion 121a, and the braking member is 121 is pressed toward the mounting groove 101d. Thereby, when the rotor arm 4 is in the line release posture, when the rotor 3 is to be rotated, the rotor 3 is rotationally braked by the frictional engagement of the mounting groove 101d of the reel body 1 with the brake member 121. In the present embodiment, when the moving member 15 is moved to the second position, the elastic member 22 is pressed against the bottom portion 121b of the engaging portion 121a, and the position of the elastic member 22 in the radial direction is adjusted by the adjusting member 23. Stable braking force can be obtained without being affected by manufacturing errors or installation errors. Further, similarly to the first embodiment, the adjustment member 23 can adjust the force of pressing the brake member 121, and the braking force of the rotor brake device 106 can be easily adjusted. Further, when the moving member 15 is moved to the second position, the elastic member 22 is disposed at a position where the braking member 121 is pressed, whereby the elastic member 22 is also formed even when the short engaging portion 121a is formed on the radially outer side. The engaging portion 121a is engaged. Thereby, the radial direction of the brake member 121 can be reduced. <Other Embodiments> The above-described embodiments of the present invention have been described. The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention. In particular, the plurality of embodiments described in the present specification can be arbitrarily combined as needed. (a) In the above embodiment, the adjustment member 23 such as a shim or a gasket is disposed between the elastic member 22 and the first protrusion 15a of the moving member 15, but the adjustment member 23 is not limited thereto. For example, as shown in an enlarged view in FIG. 8, a spring member such as a disk spring that urges the elastic member 22 inward in the radial direction may be used for the adjustment member 23. In this case, a stable braking force can be obtained, and the time adjustment work can be saved during assembly, so that the efficiency of the assembly work can be improved. Further, in the second embodiment, a spring member can be similarly used for the adjustment member 23. (b) The shape of the brake members 21 and 121 is not limited to the above embodiment. For example, the plate spring member may be press-formed to form a brake member in close contact with the reel body 1, and the shape of the engaging portion 121a may be a shape in which the elastic member 22 is engaged.
